Synthesis of 2-Channel IIR Paraunitary Filter Banks by Successive Extraction of 2-Port Lattice Sections
نویسندگان
چکیده
This paper proposes a synthesis method of 2-channel IIR paraunitary filter banks by successive extraction of 2-port lattice sections. When a power symmetry transfer function is given, a filter bank is realized as cascade of paraunitary 2-port lattice sections. The method can synthesize both oddand even-order filters with Butterworth or elliptic characteristics. The number of multiplications per second can also be reduced. key words: IIR filters, paraunitary filter banks, extraction, power symmetry

New Design of Orthogonal Filter Banks Using the Cayley Transform
It is a challenging task to design orthogonal filter banks, especially multidimensional (MD) ones. In the onedimensional (1D) two-channel finite impulse response (FIR) filter bank case, several design methods exist. Among them, designs based on spectral factorizations (by Smith and Barnwell) and designs based on lattice factorizations (by Vaidyanathan and Hoang) are the most effective and widel...
متن کاملA fast O(N) algorithm for adaptive filter bank design
Designing optimal filer banks for subband coding applications has recently attracted considerable attention [1]-[5]. In particular, the authors have developed an adaptive algorithm based on stochastic gradient descent (SGD) that enables one to optimize two channel paraunitary filter banks in an on-line fashion [3]. The idea has also been extended to the case of tree-structured filter banks [4]....
متن کاملM -Channel Paraunitary Multirate Filter Bank Factorisation over Fields of Characteristic Two
It has been proposed that all M -channel paraunitary (PU) multirate filter banks over GF(2) can be described using the product of basic lattice blocks. In this paper this conjecture is proven by considering a redefinition of degree-0 lattice blocks. A factorisation algorithm that factors all degree-J PU filter banks over GF(2) is presented. In the course of this work M -channel type-I matrices ...
متن کاملNew technique for design of 2-channel fir paraunitary filter banks
In this paper we obtain a new parameterization of all FIR paraunitary two-channel filter banks. Unlike other approaches which make use of a lattice structure or a cascade algorithm, we show that our technique provides a direct explicit expression of all FIR orthogonal filters, with no need of iteration procedures. Thus, in order to design a L-tap 2-channel paraunitary filterbank, it suffices to...
متن کاملDESIGN OF UNEQUAL−LENGTH LINEAR−PHASE FILTER BANKS WITHOUT REDUNDANCY (WedAmPO2)
In this paper, we present a new structure for linear−phase filter banks without redundancy, which have unequal−length filters at each subband. First, we extend the simplified lattice structure of the linear−phase filter bank to the unequal−length linear−phase paraunitary filter bank. In general, the unequal−length linear−phase paraunitary filter bank has equal−length filters at both the analysi...
